Boonen still uncertain

With just over a week remaining before the elite men's road race in Stuttgart, Belgium's Tom Boonen is still deciding whether the injuries sustained in the Vuelta will allow him to take the start. According to a press release issued by Boonen's Quick.Step - Innergetic team, Boonen trained for almost four hours on Wednesday and will make a final decision after another long ride on Thursday.

"My back didn't give me any trouble," said Boonen of the ride. "But I still have a few problems with my right knee as consequence of Zaragoza's crash. Tomorrow I'll be doing another long training session after which I'll be able to see my condition with respect to my participation at the World Championships."
